And a motor pulley 33 connected to the driven pulley 32 and a motor (not shown) for rotating the motor pulley 33.

On the other hand, the pair of end caps 36 are for fixing the metal fixing clamp 21 to form a predetermined interval in the support shaft 31 as shown in FIG. As shown in FIG. 6, the end shock 36 is shaped like a conventional cap having one side open and a hole 36a formed on the other side. However, as shown in the cross section, an outer ring 36b having a female threaded portion 36c formed therein and a tapered inner rune 36d are provided. The female screw portion 36c of the outer ring 36b is for fastening with a male screw portion (not shown) formed on the outer circumferential surfaces of both ends of the support shaft 31, and the tapered inner ring 36d has an inner diameter of the support shaft 31. It is inserted between the outer diameter of the metal fixing clamp 21 and for fixing the metal fixing clamp 21 to the inside of the support shaft 31 in accordance with the fastening of the female screw portion (36c) and the male screw portion. Since the inner ring 36d is for fixing the metal fixing clamp 21 and the support shaft 31 concentrically with respect to each other, the inner ring 36d does not necessarily have to be tapered. Here, the hole 36a is formed so that both ends of the metal fixing clamp 21 come out for processing.

Reference numeral 37, which is not described in FIG. 4, indicates a base supporting the above components.

In the metal fastener setting device configured as described above, the setting of the metal fastener 21 can be made simply by the hand cap 36. That is, in the state where one of the pair of end caps 36 is first fastened to the male screw formed at one end of the support shaft 31, the metal clamp 21 is inserted into the hole 36a of the end cap 36 to which it is fastened. Then, the other end cap 36 need only be fastened to a male screw provided at the other end of the support shaft 31. When the metal fixing clamp 21 and the support shaft 31 are fixed and supported concentrically with respect to each other according to the fastening of the end cap 36, when driving the motor (not shown) of the driving unit, the support shaft together with the driven pulley 32 ( 31 is rotated, so that the metal stop 31 is rotated, the ferrule located therein can be rotated together. Accordingly, the inner diameter of the ferrule being rotated is to be processed by the etching wire not shown.

In this case, the support 35b must be able to retreat back by at least the length L of FIG. 7 so that the metal fasteners 21 contained in the support shaft 31a can sufficiently escape from the support shaft 35a. .

The collet chuck 38 may be a conventionally known one, and is preferably fixedly coupled to the moving side support shaft 31b. In addition, the driven pulley 32 which rotates together with the support shafts 31a and 31b is installed at a suitable position to avoid mechanical interference with the collet chuck 38.

On the other hand, the support base 35b which has retracted back by the length L is rotated by a predetermined angle again with the pivot point as the position where it moved in parallel again or by a predetermined distance. When the predetermined angle is rotated in this manner, the collet chuck 38 can be set to be viewed from the front.

As described above, when the parallel movement or the rotation movement, the metal fixing rod 21, one side of which escapes from the fixed support shaft 31a is installed in the parallel or rotational movement position as shown in FIG. The mounting mechanism 81 is reached. FIG. 9 is a schematic left side view of FIG. 8 showing a state where the metal fastener 21 is mounted on the metal fastener mounting mechanism 81, which is a link mechanism.
